USAXS Studies of Silica Fume Additives in Cements and Concrete



Andrew J. Allen, Richard A. Livingston


Supplementary cementitious materials like silica fume, which are added to the cement mix and react with calcium ions in the pore solution, enhance the production of calcium-silicate-hydrate gel and modify the microstructure in other ways. By combining ultra small angle x-ray scattering (USAXS) experiments on silica fume slurries with small-angle neutron scattering (SANS) experiments on hydrating cement systems, the effects on the microstructural development during cement hydration of adding silica fume have been studied.
